My bank sold a local branch to another bank (in the state of Wisconsin, United States of America), including my accounts, without my permission. My first knowledge of it was that my debit card was declined. Calling my local branch during business hours only got an answering machine under the new bank's name.
I went home, checked 8 months or so of envelopes from the bank, and saw zero pertinent information.
Today I finally got through to a human at my old bank's customer service. Their position: you are no longer a customer, we don't have your accounts. Would you like the new bank's customer service number?
And, yes, I got middle-sized envelopes from my "new owner" twice over the last month. I didn't open them, just as I don't open the offers from other banks that I'm not a member of, insurance companies I have no policies with, car repair scams, etc.
So, how is any of this legal? There is another branch of my old bank about as far from me as my new one. There are branches all over the state I could have used. Why can't I keep using any of them? When I set up my accounts I had to sign papers: I have signed no papers with this new bank, why do they have a right to my accounts? Not to mention my personal information, which presumably has now been transferred without my permission to a third party that I have never seen a privacy policy for, all without my permission.
